Design a Graphic

I am looking for someone who can make me an image that is roughly a long arrow that curves back in on itself. This arrow is wider on one end than on the other. The wide back end will start in a reddish color. The pointed end of the arrow will be in green. The colors must transition from red to green, with yellow after red and some other color between yellow and green. I would hope the transition can be made continuous. I have attached a document that will help you better understand what I am trying to do. I can explain my request if we imagine the image on this document to be of the face of a clock. We will work our way backward on the clock face. As you can see in the image, the center is open and the line tapers from beginning (red) to end (green). I would like some general representation of an arrow pointing up toward the red part from the end of the green part. At 2 o'clock, you see the items vaguely connected by red. Those items go from there, backward, to approximately 10 o'clock, where they connect to the items in yellow. The yellow bits run to about 7 o'clock where they transition to what is currently in blue from approximately 6:30 to 5:30 on the clock face. Green picks up from 5 to almost three, with an added "arrow" extending up toward the center line, pointing vaguely toward the red area. Whereas the colors transition from red to green, I would like the shading to be a gradient from light to dark, with the parts of the image toward the center of the graph lighter and the edges darker. You can see how the shaded areas generally aggregate toward the outer edges. The final graphic should be shaped more like a doughnut than is this original. In other words, the colored/shaded area will be wider than the hole in the center. I have given careful instructions because I do not believe this to be a particularly confusing or difficult project. I am looking for the most attractive combination of price and quality. Also, anyone who chooses to provide a low-res mockup will be given extra consideration. Thank you.
